At higher energies, the \(>\) 5.2 keV ENAs measured by Cassini/INCA have shown the existence of a "Belt" of varying ENA intensities identified as relatively wide and nearly energy-independent ENA region that wraps around the celestial sphere and two "Basins" where the ENA minima occur [1]}, [2]}. Both these features have been proven undeniably to be of IHS origin [1]}, [4]}, [2]}, [6]}, [7]}, [8]}, [9]}.
